United States Patent 2,899,109 PA on TANK A ND" msrnusnro LINER THEREFOREdwardStanfield-Shorkey, Grosse Point Wood, Mich., a'ssignor 'toContinental FGan Company, Inc., New York, N .Y,, .a corporation of NewYork Application danuary 15, 1958, Serial-No. '7095033 Claims. -.(Cl.222-183) l he tinventionrelate's:generally todispensing containerstructures and primarily seeks to provide a novel paint tank and linerarrangement wherein paint can be mixed :to proper=consistency,=colorandshade without-direct'contact of the :paint with the interior of :thetank, and then conveniently dispensed 'through a funnel like extensionof the liner extended through a clearance opening in a wall of the tank.

In the mixing'of tpain't =ithas been'eommon practice to put the paint.in .an open tank, fintroduce thinning :and other conditioning :liquidsand pigments into the paint and-paddle stir or .agitate themix in orderto obtain the desired consistency, color and shade. This practicerequires that the tank be thoroughly "cleaned after every use in orderthat the obtainingof'desired two color and shade insubsequentlysmixed:batches will not be rendered difficult or inipossibleby contact oftheypaint being mixed with remnants *of a previously mixed batch aof:paint clinging to the interior walls of the tank. Naturally there is aconsiderable labor loss in the necessary cleaning of tanks andzitiis apurposeofithe present invention to avoid the problems of the.statedcommon ,practice by providing a novel mixing tankhaving alinerplaceable in the tank before each mixing operation zto iprevent directcontact of the paint with the interior walls of the tank, :saidlinerhaving :a funnel=like extension projected through an opening in :a wall.of .the .tank and through which the mixed ipaint .canbepoured out withfacilityoifter the mixing-op- \e'ration and lbeing removable as a wholefrom :the tank for substitution of another clean liner prior to anothermixing operation, and disposable or subject to a suitable cleaningoperation.

Another object of the invention is to provide a tank and linerarrangement of the character stated wherein the paint dispensingextension of the liner is in the form of a generally triangular flapextension projected through an opening in a wall of the tank and foldedflat against a tank wall portion exteriorly of the tank and attached tosaid wall portion.

A further object of the invention is to provide a liner structure of thecharacter stated wherein the extension initially is sealed againstegress of paint but includes a corner portion subject to being cut oilto provide the desired paint dispensing opening.

A still further object of the invention is to provide a tank and linerarrangement of the character stated wherein the tank and the liner aregenerally rectangular in shape, each having opposed end and side wallsand a bottom, the tank having a dispensing opening near the bottom in atleast one wall thereof and the liner having a dispensing flap extensionon at least one Wall thereof in position for being projected through thedispensing opening in a tank wall and be removably attached to saidwall.

With the above and other objects in view that will hereinafter appear,the nature of the invention will be more clearly understood by referenceto the following detailed description, the appended claims and theseveral views illustrated in the accompanying drawings.

Figure 3 is a vertical longitudinal sectional view illustrating :thetank of Figure l with the liner of Figure 2. mounted therein, thefunnel-like flap extensions of the liner :being projected throughdispensing openings formed in the tank ends and turned up againstexternalwall por- 'tions of-the tankand removably attached thereto.

-Figure4 is a view similar -to Figure 3 showing oneof :thefunn'el-likeflaptextensions released from its temporary attachment tothe tank wall lowered into position :for

dispensing paint from the tank.

Figure 5 is an end elevation of the tank structure .shown in Figure '3.

Figure -6 is a fragmentary perspective view illustrating one corner ofthe tank with the liner folded down over the open top-edge portionof thetank.

.-In :the example of embodiment of the invention .herein disclosed, themixing tank generally designated 5 is 're'c ttangular in shape andincludes opposed end walls 6, op- \POSEd side walls 7 and 'a bottom wall3. A dispensing qpeningvisformed in-oneof said walls near the bottom,said opening being indicated at 9. In the example illustration, tthedisp'ensingopening 9 is formed in one of the end walls 6, and ifdesired, such an opening can be provided in'each of the end walls 6 asshown inFigure's 1, 3 and 4.

The liner, shown in detail in Figure 2, and generally designated :10 maybe stormed in any approved manner from flexible =film such :as:polyethylene. The particular manner of fabricationof the liner is of nomaterial importanceexcepttortthe provision'ofthe funnel-like extensionswhich are to extend through the tank openings '9 and serve as dispensingmeans. In the particular dis- :closuretherein 'made, :the liner includesopposed end walls 11, opposed side walls 12 and a bottom 13. Flapextensio'ns 14 which are tunnel-like in shape are provided at .each endof the liner in position for projecting through Fthe tank openings9rl11-th6 manner clearly illustrated in Figures .2, 4 :and 5. While theliner may be formed in various ;ways, lit may be Eformed by folding upthe :sides 12 from a single blank also including the bottom 13 and thetriangular extensions for forming the bottom ply of the funnel-like flapextension 14. Each end 11 could have a triangular extension to form theupper ply of the funnellike extension 14, the engaging marginal edges ofthe end and side walls and those of the opposing triangular plyextensions being heat sealed together to secure the assembly in themanner illustrated in Figure 3.

When two dispensing extensions or funnel-like flaps 14 are provided theycould be selectively projected through a single tank opening 9, theprojecting extension being folded up against the tank end wall as at 15and adhesive tape secured at 16 to said end wall. The other extension 14could be folded up inside or between the liner end wall and adjacenttank end wall, or should the tank be provided with two openings 9 asindicated in Figure 1, both funnel-like flap extensions could beprojected through the openings and secured against the respective tankend walls by the tape as indicated at 16 in Figure 3.

When it is desired to dispense paint from the tank, the tape 16 at thedispensing end is torn away and the funnel-like extension flap islowered as shown in Figure 4. By then cutting off the closed end orcorner, as by cutting across the dotted line at 17 in Figure 2, anopening can be provided through which the paint can be dispensed in themanner clearly illustrated in Figure 4. It is desirable to fold theliner down over the open top edge of the tank, as at 19, as indicated inFig r s 3. 5 n 6 f.

the drawing, and by thus providing and mounting the mixed batches andaltering the desired color or shade thereof.

It is to be understood that should the tank be mounted on a tumblingmeans during the mixing of the paint, a suitable closure (not shown) canbe applied over the open end thereof.

While a preferred form of the invention is disclosed herein, it is to beunderstood that variations in the form and arrangement of the parts canbe effected without departing from the scope of the invention as definedin the appended claims.
